At-Tawbah 9:47

لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًۭا وَلَأَوْضَعُوا۟ خِلَٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّٰلِمِينَ

If they had come out with you, they would not have added to your (strength) but only (made for) disorder, hurrying to and fro in your midst and sowing sedition among you, and there would have been some among you who would have listened to them. But Allah knoweth well those who do wrong.
